Given numbers are 153, 172, 85, 887

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(153, 172) = 26316

GCD(153, 172) = ( 153 x 172 ) / 26316

= 153 / 172

= 153

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

Step3:

LCM(1, 887) = 887

GCD(1, 887) = ( 1 x 887 ) / 887

= 1 / 887

= 1

So, Greatest Common Divisor of 153, 172, 85, 887 is 1
